Good until the end of day on Tuesday FEB-26-2019 in the pacific time zone, promo code SURPRISE2 gets you 20% off most Monoprice brand products priced over $500, and among them is the Monoprice Electrostatic Headphone System which, thanks to the coupon discount, drops from $700 to $560. It also comes with free standard US shipping.

It has one detailed customer review over there, so for more on it, your favorite audio forums, websites and search engines are your e-static friends 🙂

The Monoprice Monolith headphone party continues with a new open-back electrostatic headphone system, now in-stock for $699 plus shipping. This comes with a portable headphone amplifier. Audio comes in (to the amp) from a 3.5mm audio input and goes out to the headphones through the electrostatic headphone jack.

I promise this is the last time I’ll use this joke! Come on Barbie, let’s have an Electrostatic Party! In progress at Massdrop, as part of their growing co-operation with Wisconsin’s KOSS, they are offering the new condition Massdrop x Koss ESP/95X Electrostatic System for $500 with free US shipping and subsidized international shipping. Choice of 120V or 220V is available at checkot.

This is a “massdropized” variation of the well-known ESP-950, but it is an in-development product. Shipment is early April 2019, that’s over five months from blog-posting date.

A total of 713 are offered for purchase. As of the time of 379 of them have been sold.

Come on Barbie, Let’s Have an Electrostatic Party! Fully unlocked at Massdrop, and with only 45 units available (14 claimed as of the time of writing), you can get the new condition KOSS ESP950 Electrostatic Headphone System for $600 with free shipping. It is estimated to ship mid-December 2017 from the vendor with the usual Koss limited lifetime warranty.

This is not the only Koss-Massdrop partnership, they also offer the Massdrop x Koss Porta Pro X for $38 with free shipping as one of their “In-Stock Drops”. These are sold like a regular online purchase (the “drops” open/close every 24 hours and items purchased during a 24 hour window get shipped in a couple of business days after that). We are tracking the “in-stock drops” in our new Massdrop Tracker.

Another crowd-funded hybrid-electrostatic headphone line are the Mitchell and Johnson, whose name may remind some of name-brand shoes from the GQ ad pages 🙂 Regardless, two of their GL-series portable hybrids are available in USED condition at Amazon Warehouse Deals as follows:

The new condition SHARKK Bravo hybrid electrostatic headphones are currently down to $50 with free shipping by BREED through amazon.com. These ship directly from BREED (that’s the marketplace seller name) and they are not Prime eligible.

These were a crowd-funding model that went for $250+ but have their basket of issues. Still, whether you want them at $50, it’s up to you ~ check reviews and comments and such.

This was a crowdfunding project that did not become an audiophile blockbuster, but if you read up on them and you are curious enough to test/compare them, the SHARKK Bravo hybrid electrostatic closed-back over-ear headphones are available in new condition for $50 with free shipping by marketplace seller “BREED” through amazon.com. They ship directly from BREED and they are not Prime eligible.

The headphones average 3.5 out of 5 based on 26 customer reviews. Their starting price was $300.

The price keeps on dropping for these, but do read reviews if you are not familiar with them as they have trade-offs and complaints! It is the new condition SHARKK Bravo Hybrid Electrostatic Headphones now down to $65 with free shipping by BREED on eBay (ships from Florida).

The Mitchell and Johnson GL1 hybrid-electrostatic portable headphones go for $200 in new condition, but if you are comfortable with used headphones, they go for $140 in “Used – Very Good” condition (scratches, original packaging) through Amazon Warehouse Deals.

The planar world is getting too crowded, so now companies are moving into less cultivated crops, electrostatics 🙂

This Kickstarter Electrostatic hybrid was not greeted as a liberator by audiophiles, so its prices keep on falling. If you have read about it, it being the SHARKK Bravo Headphones Hybrid Electrostatic Headphones, do read the reviews, and you are comfortable with its trade-offs but you are still curious and want to buy it, coupon code PBACK2SCHOOL20 drops it from $90 to $72 with free shipping BREED on eBay (98%, Miami). Coupon expires 7/17/17 at 3am ET and it is part of this eBay promotion.

If you are curious about the relatively recent SHARKK Bravo Electrostatic Hybrid headphones, they are currently down to $120 with free shipping by seller “BREED” through Amazon.com. They are not Prime eligible. Another seller there has it for $100 in refurbished condition.

If you are not familiar with these, be sure to read up on reviews before buying as they have their trade-offs and issues. Which is partially why the price has been dropping 🙂

Come on Barbie, let’s have an Electrostatic Party! Mayhaps I need to start a Patreon where people can donate to block me from repeating jokes like this one 😉 Regardless, the new condition Koss ESP-950 Electrostatic Stereophone is on sale again, going for $625 with free shipping by Amazon actual. Limit one unit per customer at the moment. This is a system, you get the headphone and matching amp, unlike most headphones out there.

The Koss ESP-950 electrostatics go for $650 in new condition, but if you are comfortable with used, you can get them for $519 in “Used – Very Good” condition (this sold out as of a 12/3/16 recheck) for $552 in “Used – Like New” condition, both by Amazon Warehouse Deals actual. The former has minor cosmetic imperfections, which is probably why it has a lower used rating.

I promised I would stop saying this too (“Come on Barbie, let’s have an Electrostatic Party!”) but apparently I can’t help myself 🙂 The new condition Koss ESP-950 Electrostatic Stereophone is back on sale again, going for $649 with free shipping at Amazon by Amazon actual with a limit of five units per customer.

This is dead… UPDATE 5:55pm ET: as of this update, it looks like Amazon yanked their own listing, and only marketplace sellers are offering it for $1000+ in new condition. Since the listing is yanked, in theory the sale may not be over, since Amazon’s own price did not go up, it just evaporated. But realistically, it should be considered dead…

The Koss ESP-950 Electrostatics are on sale in new condition for $800 with free shipping at Amazon.com. They are offered at this price by both Amazon actual and by the Koss store. Both options are Prime eligible. These headphones come with their dedicated amp. They average 4.2 out of 5 based on 25 customer reviews.

Even though it sounds totally ridiculous, I can’t resist saying “Come On Barbie, Let’s Have An Electrostatic Party!”. With that out of the way, the Koss ESP-950 Electrostatic Stereophone is on sale for around $735 at Amazon.com. Amazon’s own price is $736 while marketplace sellers go for as low as $733. The same price range can be found outside Amazon by World Wide Stereo on eBay and Sonix Electronix.

Come on Barbie, let’s have an Electrostatic party! You can’t unread that line, but you can get the new condition Koss ESP-950 Electrostatic Stereophone for $824 with free shipping, with a limit of five per customer, at Amazon.com by Amazon actual. It averages 4.2 out of 5 based on 21 customer reviews and has four questions answered. This is not a lightning deal, so the price is market driven or manufacturer-promotion driven.

More action at the members-only but free-to-join Massdrop website. Of the latest offers, one is fully unlocked (lowest price possible), the xDuoo TA-01 DAC/Amp goes for $135 shipped (expires in five days from today). The items below are not fully unlocked as of the time of writing of this blog-post:
